Description
Technical field
The utility model relates to field of LED illumination, in particular, and a kind of LED light device.
Background technology
Along with the quickening of modern life rhythm and the raising of quality of life, life content is more and more rich and varied, the house of people's live and work, school, office, street, market, factory and enterprise and all kinds of public place, all employ all kinds of lighting, wherein importantly incandescent lamp and fluorescent lamp.
Fluorescent lamp utilizes THE FILAMENT DISCHARGE AND, make the inert gas in fluorescent tube and mercury vapour produce ultraviolet, thus the fluorescent material of exciter lamp inside pipe wall makes a kind of lighting of its luminescence.It is based on incandescent lamp after revolution.Fluorescent lamp not only economizes on electricity compared with original incandescent lamp, the efficiency of illumination is high, and long service life.Fluorescent lamp service life is 10000 hours, and luminous efficiency can reach 26% of input energy, and throw light on soft, dazzle is little, and light efficiency is at about 50lm/w; And only have 1000 hours the service life of incandescent lamp, available light energy probably only has 2%-3%, and most energy loses in the form of heat, and light efficiency is about about 9lm/w.
Because fluorescent tube contains a large amount of inert gases, mercury vapour and fluorescent material, there will be in production and use procedure unavoidably and evaporate into phenomenon in air, cause environmental pollution.Secondly, in fluorescent lamp circuit, employ ballast, starter, need a large amount of silicon steel sheets and copper cash, improve cost and power consumption, and produce a large amount of high-intensity magnetic field, cause electromagnetic interference.
Illumination is one of main energy resource consumption mode, and according to statistics, the lighting energy consumption in the whole world has accounted for 1/5th of world's total energy consumption.China has just again and again met with the crisis of electricity shortage from the beginning of this century, and especially along with the development in epoch, resident and commercial power demand constantly increase, and existing supply of electric power can not meet people's lives and industrial needs far away.China can save the New Product of energy resource consumption in the urgent need to one, to solve the problem of supply of electric power deficiency.
China is the production and consumption big country of incandescent lamp, looks into according to middle information business network regulation, and within 2013, China's incandescent lamp output has reached 4,600,000, and Chinese electric consumption on lighting accounts for about 12% of Analyzing Total Electricity Consumption.If incandescent lamp all replace with energy-saving lamp, can economize on electricity in year a large amount of electric energy, and energy-saving and emission-reduction have a high potential.
LED has fabulous power savings advantages, light efficiency can reach 100lm/w, it is about 10 times of incandescent lamp, specialty research shows the LED electricity-saving lamp of 12 watts, within the time of use 50,000 hours (five and half), compared with 60 watts of incandescent lamps that can send identical light, consume 2400 degree of electricity less, save nearly 1200 yuan of fund.Chinese population radix is large, and the usage quantity of bulb is surprising especially, if national people use energy-conservation LED illumination lamp, brings huge economic benefit by for the electricity needs in China's high speed development and application.
Therefore from 2008, China just starts to advocate use energy-saving illumination, and has dropped into the incandescent lamp that a large amount of manpower, material resources and financial resources widely popularize energy-saving illumination replacement high energy consumption in China, to realize the more efficiency utilization of national electric power and less waste.The popularization of China's energy-saving illumination in recent years has achieved gratifying achievement, greatly reduces the pressure of national grid.On August 8th, 2011, the China national Committee of Development and Reform discloses " China eliminates incandescent lamp route map (exposure draft) ", and thoroughly will eliminate by 2016 and use general lighting incandescent lamp, the energy efficient lighting system being representative by LED is replaced.
LED mainly adopts the wafer of a piece very little to be encapsulated in inside epoxy resin, and it is very little, very gently.The wafer that its core is made up of p-type semiconductor and n-type semiconductor, has a transition zone, is called p-n junction between p-type semiconductor and n-type semiconductor.In the PN junction of some semi-conducting material, the minority carrier of injection and majority carrier compound tense can discharge unnecessary energy in the form of light, thus electric energy is directly converted to luminous energy.PN junction adds backward voltage, and minority carrier is difficult to inject, therefore not luminous.
This diode utilizing injection electroluminescence principle to make, light emitting diode, is generally called LED.When it is in forward duty (two ends add forward voltage), electric current flows to negative electrode from LED anode, and semiconductor crystal just sends the luminous ray of different colours, the power of light and current related.
Traditional incandescent light fitting can produce a large amount of heat energy, and its energy utilization rate is extremely low, and a large amount of electric energy has been wasted by becoming heat energy.Containing a large amount of mercury vapours in fluorescent lamp, if broken mercury vapour, can evaporate in air.
LED is solid luminescence light source, and use chemiluminescence technology, electric energy is almost all converted to luminous energy, and luminous efficiency is high, can not cause the waste of the energy.Further, LED does not use mercury, and product is not leaded yet, and relative fluorescence lamp plays a protective role to environment, is Green Product.Compared with fluorescent lamp, LED, without the need to ballast, without the need to starter, without stroboscopic, noiselessness, is not only applicable to family, is more suitable for school, library, office and all kinds of public place.
The illumination of LED is equivalent to more than five times of Same Efficieney conventional lamp illumination, energy-efficient.LED illumination lamp power consumption is quite low, and the operating voltage of each monomer LED is 2-3.6V.Operating current is 0.02-0.03A.In other words: the electric energy of each monomer consumption is no more than 0.1W.LED lamp power consumption is less than 1/3rd of Same Efficieney conventional lamp.
Owing to using direct-current working volts, can not scintillation be produced, be conducive to reading, handling official business and daily use.Illuminator itself use epoxy resin and and unconventional glass, firm firm, can not damage easily, can use relievedly.Not containing ultraviolet in light source light spectrum, safe and reliable.Actual life can, more than 100,000 hours, be 10 times of conventional lamp usually.
It is typical Green Product that LED illumination lamp internal characteristics determines it, is also scientific and technical innovation product of new generation.It is the perfect light source replacing traditional lighting utensil, has a wide range of applications.
But existing LED lamp also has following several deficiencies:
1, solid luminescence, causes non-uniform light.The luminescence of common LED illuminating lamp is by being encapsulated in the very little LED wafer (i.e. LED luminescence chip) of one piece of block inside epoxy resin, and wafer volume very little is solid state light emitters.Luminescent device is by arranged evenly uniformly, and a lot of empty position and not luminous appears in the distance between device, and cause whole lamp body non-uniform light, device and room form the luminous contrast of bright spot and blackspot, and producing human eye stimulates, and is easy to tired.
2, use opalescence lampshade, reduce luminous efficiency.In order to solve the problem, an opalescence hemispherical light guide lampshade can be increased in alight body front portion.Although this method solves luminous uniform problem, the lampshade made due to opalescence material has larger absorption to light, causes the loss of light, reduces the luminous efficiency of light fixture.User, in order to reach same illumination, haves no alternative but adopt more powerful light fixture, not only makes the use cost of user improve, the more important thing is the consumption increasing the energy, thus cause the waste of the energy.
3, the LED lamp with secondary light-distribution is adopted.In order to overcome the deficiency of opalescence cover mode, a kind of alternative scheme adopts secondary light-distribution function, namely before light fixture, increases a transparent light-distribution lens, presses the structure of light fixture and contain one or more different sub-camera lens in lens.Every sub-camera lens all designs for corresponding LED component, carries out secondary light-distribution, to reach the optimum efficiency of luminous intensity distribution to the LED of light fixture.The light that this light fixture can make LED send, carry out the effect of mixed light through compound lens, reach from the light of lens injection evenly and without blackspot effect, and have employed transparent material and make lens, light does not have loss substantially, is a kind of solution of good secondary light-distribution.This method need increase a luminous intensity distribution compound lens, and lens need carry out corresponding design and fabrication according to the concrete structure of each light fixture and LED quantity difference.Because light fixture various combination lens are also different, each compound lens can only be that a kind of light fixture is supporting, and the mould producing lens also can only be that a kind of product uses, and this just makes the cost of lens not easily reduce, and the result brought is that the cost of light fixture is not low yet.When each LED component is luminous, can produce certain heat, due to the more LED component that distributes in lamp body inside, multiple luminescent device closely, will produce heating problem and must solve, otherwise the time one is long, can have a strong impact on the service life of LED.
Such as, as shown in Figure 1, the installing plate 110 of LED lamp 100 arranges a lot of LED wafer 101, light emission direction is concentrated, and lamp body non-uniform light, illuminating effect is poor.
And for example, as shown in Figure 2, a lot of LED wafer 101 of arranged in matrix on the installing plate 110 of LED lamp 100, lamp body non-uniform light, heat is concentrated, and is difficult to heat radiation, there is potential safety hazard.
Therefore, prior art existing defects, needs to improve.
